Be it known that I, FRANK A. CORTIS, a citizen of the United States, and a resident of Meriden, in the county of New Haven and '5 State of Connecticut, have invented certain new and usefullmprovements in Lamp-Burners, of which the following is a full, clear, and exact description, whereby any one skilled in the art can-make and use the same.

My invention relates to the class of devices used for producing an incandescent light from hydrocarbon oil; and the object of my invention is to provide a device ot' this class extremely simple and cheap of construction and edective in operation.

To this end my invention consists in the device as a whole, in the combination of parts, and in the details and their combination, as

A hereinafter described, and more particularly ze pointed out in the claims.

Referring to the drawings, Figure lis a View in side elevation of a device embodying my invention with parts cut away to show construction. Fig. 2 is a detail view,in central 2 5 vertical section, through the burner. Fig. 3 is a detail view in cross-section through the v,same on a plane above the generating-coil.y

Fig. 4 is a View in cross-section of the same on aplane located immediately below the edge 3o of the jacket.

In the accompanying drawings the letter ct denotes a reservoir 0r like source of supply for a hydrocarbon fluid, and b a supply-pipe leading therefrom and having a valve c, by

3 5 means of which `the [iow'of fluid may be controlled.

The letter CZ denotes a mantle common to the class of devices for producing an incandescent light and supported on a rod e., the 4o lower end kof the mantle embracing a collar f, mounted on the burner-tube, all of these parts being' of ordinary construction and forming no part of the present invention.

The letter g denotes the body part of the burner, having an upward extension forming a burner-tip g, within which is a chamber h, anda shank g2, forming a mixing-chamberz'. The collar f is supported on the extension g', and a netting f overlies the mouth of the 5o burner, as is common in devices of this class.

In the form of the device shown a tube g3 is secured within the shank g2 of the body part, forming an'extension of the mixing-chamber;

but it is obvious that the shankv g2 may be i' ,being left between the bridge and the jacket for the entrance of air to support combustion.

A vaporizing-tube o extends from the supply-pipe l) upward through the bridge andV through the nut 7c into the heating-chamber l.` This vaporizing-pipe is preferably coiled about the shank g2 of the body part, forming a vaporizing-chamber 0. vThe pipe then eX- tends downward through the nut 7c on the 0pposite side from that through which it passed upward and into the bridge fn. An opening in the side of the pipe communicates with a passage n in the bridge, which leads to the nozzle p, opening into the mixing-chamber, the opening through this nozzle being controlled by the ordinary needle-valve q. The bridge n is cut lengthwise into the opening through which the vaporizing-tube o is l0- cated, a clamp-screw n2 beingused to draw the parts of the bridge together and clamp the tube in position.

A support r for the rod c is secured to the body part g, preferably by bein g screwed into the same, and this support may be used as a means of holding the jacket min position, a clamp-screw fr' serving as a means for adj ustin g the rod c vertically.

By myyimproved device an extremely-simple means of constructing a vaporizing-chamv ber is provided, the area of the heating-chamber beingeasily varied to graduate the heat therein by simply rotat-ingthe body part g of the burner.

Y I claim as my invention- 1. In combination with a fluid-supply for an incandescent burner, a burner-tip, a mixing-chamber appurtenant to the burner-tip, a nozzle opening to the mixing-chamber, a

single length of pipe extending into an in-jA ,the other whereby the area of the heatingchamber is Varied, and a single length of pipe extending into the heating-chamber.

3. In an incandescent burner, in combination, a body part, a burner-tip supported thereon,a mixingchamber located in the body part, a jacket inclosing the body part, a nut located within the jacket said jacket and nut being adjustable with reference to each other whereby the area of the heating-chamber is varied, a supply-passage extending into the heating-chamber, and means for supplying uid to the mixing-chamber.

4. In an incandescent burner, in combination, a body part terminating in a tip, ashank forminga mixing-tube, a nut fitting the screwthreaded surface of the shank and forminga heating-chamber, a supply-passage located within said chamber, and means for supplying fluid to the mixing-chamber.

In an incandescent burner, in combination, a body part having a burner-tip and a shank forming a mixing-chamber, a nut secured to the shank by means of interengaging screw-threads and forming a heatingehamber, a supply-pipe extending into the heating-chamber, a jacket extending between the nut and the body part inelosing the heating-chamber, and means for supplying fluid to the mixing-tube.

G. In an incandescent burner, in combination, a body part, having a tip and a shank forming a mixing-chamber, a nut secured to the screw-threaded shank and formingaheating-chamber, a jacket inclosing the heatingchambcr, means for holding the nut against relative rotation with the shank, a supplypipe extendinginto the heating-chamber, and means for supplying fluid to the j mixingchamber.

7. In an incandescent burner, in combination, a body part having a burner-tip and a shank forming a mixing-tube, a jacket surrounding the body part and `extending therefrom, a nut secured to the screwthreaded shank and located within the jacket, a supply-pipe extending through the nut into the heating-chamber formed between the body part and the nut, and means for supplying fluid to the mixing-chamber.

S. In an 'incandescent burner, in combination, a body part having a tip and a shank forming a mixing-chamber, a nut located on the shank and forming a heating-chamber and adjustable lengthwise of the shank, a jacket sn rronnding the body part and nut and `forming walls for the heating-chamber, a single length of pipe extending from a source of supply into the heating-chamber about the same and to a passage leading to a nozzle, and the nozzle located appurtenant to the mixing-chamber.
